The image manager has a grey screen bug (probably when network unreachable)

What

• The image manager has a grey screen bug (probably when network unreachable, did that in the subway this morning)
• https://github.com/openfoodfacts/openfoodfacts-server/assets/1689815/7de9beaf-5514-490e-bf17-23b182791e95

@teolemon Escaped from the subway now? Still see the same bug?
It looks like a NPE to me.
I'll try to reproduce it. Maybe it depends on the metro line. Was it line 13? 😉

@teolemon You're right, without an internet connection it fails if you click on "select an existing image".

@g123k It looks like it may have to do with the new "deep-linkable" navigation, or something like that:

Interesting, I will check that.
@teolemon This morning, do you remember the error with the Mojito syrup?
I think it was another one, isn't-it?
